Everton manager David Moyes has confirmed that Republic of Ireland midfielder Darron Gibson will be sidelined for up to five weeks with a thigh strain. Gibson had started all three of Everton\'s Premier League games so far this season, but his injury means he could miss their next six matches. The 24-year-old, who joined Everton from Manchester United in January for an undisclosed fee last season, suffered the problem in the first half of Everton\'s 2-0 defeat at West Bromwich Albion before the international break. \"Darron\'s got a thigh strain and will probably be out for four to five weeks now,\" Moyes said. \"He\'s had two weeks now so hopefully we are a couple of weeks down the line already because of the international break.\" Gibson recently told Republic of Ireland manager Giovanni Trapattoni he was still suffering from the disappointment of playing a limited role at UEFA EURO 2012 and did not want to be considered for selection in their 2014 FIFA World Cup™ qualifying campaign.
